Egyptian antiquities officials say they have confirmed the existence of a hidden internal corridor above the main entrance of the Great Pyramid of Giza. Video from an endoscope showed the inside of the corridor, which is 9m (30ft) long and 2.1m (7ft) wide.
A new chamber dating back some 4,500 years has been uncovered in one of the Great Pyramids in Egypt. The corridor measuring nine metres (30ft) long and more than six feet wide was discovered close to the main entrance of one of the three pyramids at Giza.
To build such a pyramid today (using modern technology and equipment such as cranes and helicopters), it would take 1,500 to 2,000 workers around five years, and cost around $5 billion.
Considering the pyramids were built more than four thousand years ago, the exact technique of construction remains a mystery and modern-day equipment was not available at the time. It is believed that ancient Egyptians ferried the huge stone blocks on the Nile river.
The images reveal a corridor with a vaulted ceiling, presumably one that was hasn't been seen by humans since the pyramid was built more than 4,500 years ago. The corridor's purpose is still unclear. Muons are created when high-energy particles from space called cosmic rays crash into the Earth's atmosphere.
On Thursday, Egyptian officials announced the discovery of a hidden corridor above the pyramid's entrance. Measuring 30 feet long, the passage could serve as a jumping-off point for additional research into the mysterious inner chambers.
The construction of the pyramids is not specifically mentioned in the Bible. What we believe about their purpose does not impinge on any biblical doctrine.
Many people have said that the pyramids would last 1 million years or even until the world ended, but I'd say around 10,000 to 100,000 years based on current observations.
The Sphinx is home to a number of tunnels and passages. Some were created by treasure hunters, others by people re-carving the Sphinx, and others are unknown. There is even a shaft at the top of the Sphinx's head. There are even reportedly access tunnels to some large and natural caves directly under the Sphinx.
Giovanni Battista Caviglia, led 160 men in the first modern attempt to dig out the Sphinx. They could not hold back the sand, which poured into their excavation pits nearly as fast as they could dig it out. The Egyptian archaeologist Selim Hassan finally freed the statue from the sand in the late 1930s.
Legend has it that there is a maze below the paws of the Sphinx that leads to the mystery-shrouded Hall of Records, where all essential knowledge of alchemy, astronomy, mathematics, magic and medicine is stored. The library of knowledge - researchers continue to search for it today.
Inside the Great Pyramid Of Giza, there is a massive void. The room, sealed when the pyramid was completed some 4,500 years ago, is of unknown purpose, though some have speculated it could be a secret burial chamber of the pharaoh Khufu, who ordered the pyramid to be built.
One of the biggest mysteries about the Egyptian pyramids is the construction techniques used to erect them. The incredible feat of the Egyptians is all the more impressive when taking into consideration that over 2 million limestone and granite blocks were used to build the Great Pyramid of Giza.
One of the biggest mysterious concerning the great pyramids is the big void in the great pyramid of Khufu, it is a chamber above the king's chamber around 100 feet (30 meters) and appears to have not been entered or damaged by tomb raiders.
In the 12th century, Kurdish ruler al-Malek al-Aziz Othman ben Yusuf attempted to destroy one of the pyramids, but only successfully damaged the smallest, leaving a vertical gash on the north face.
